Abstract: In 2009 in The Lancet, Jeffrey Koplan and colleagues provided a new definition for global health and proposed several distinctions between global health, international health, and public health. This attempt to distinguish differences between global health and public health conflicts with the key tenets of a global public health strategy. These tenets offer the foundation of a redesigned global health system that could accomplish the optimum level of health for populations. This approach has profound implications for training, scholarship, and practice necessary to improve human health.

Determining research knowledge infrastructure for healthcare systems: a qualitative study
Authors: Moriah E Ellen, John N Lavis, Mathieu Ouimet, Jeremy Grimshaw, and Pierre-Olivier Bédard.
Abstract: This study examines research knowledge infrastructures (RKIs) found in health systems. An RKI is defined as any instrument (i.e., programs, interventions, tools) implemented in order to facilitate access, dissemination, exchange, and/or use of evidence in healthcare organisations. Based on an environmental scan (17 key informant interviews) and scoping review (26 studies), we found support for a framework that we developed that outlines components that a health system can have in its RKI. The broad domains are climate for research use, research production, activities used to link research to action, and evaluation. The objective of the current study is to profile the RKI of three types of health system organisations--regional health authorities, primary care practices, and hospitals--in two Canadian provinces to determine the current mix of components these organisations have in their RKI, their experience with these components, and their views about future RKI initiatives.

Neglected diseases, civil conflicts, and the right to health - April 13, 2011 - 12:00 p.m.
Authors: Chris Beyrer, Juan Carlos Villar, Voravit Suwanvanichkij, Sonal Singh, Stefan D Baral, Edward J Mills
Abstract: Neglected diseases remain one of the largest causes of disease and mortality. In addition to the difficulties in provision of appropriate drugs for specific diseases, many other factors contribute to the prevalence of such diseases and the difficulties in reducing their burden. We address the role that poor governance and politically motivated oppression have on the epidemiology of neglected diseases. We give case examples including filariasis in eastern Burma and vector-borne diseases (Chagas disease, leishmaniasis, and yellow fever) in Colombia, we show the links between systematic human rights violations and the effects of infectious disease on health. We also discuss the role of researchers in advocating for and researching within oppressed populations. Full article text.

Plasmodium falciparum parasite infection prevalence from a household survey in Zambia using microscopy and a rapid diagnostic test: Implications for monitoring and evaluation - February 7, 2011 - 2:00 p.m.
Abstract: This paper presents estimates of P. falciparum infection prevalence in children under 5 years old in the context of a population-based household survey in Luangwa District (Lusaka Province), Zambia, an area where greater than 75% of households possess at least one insecticide-treated mosquito net (ITN). The sensitivity and specificity of an HRP-2 rapid diagnostic test (RDT) (ICT Malaria Pf) compared to microscopy, as well as factors associated with discordant diagnostic results are also presented. P. falciparum infection prevalence was estimated at 7.0% (95% CI 4.9-9.0%) using microscopy. Using microscopy as the gold standard, the sensitivity of the HRP-2 RDT was 100% and specificity was 91.5%; positive predictive value was estimated to be 46.7% (95% CI 36.3-57.4%). RDT discordance, or HRP-2 false positivity, was highest among older children, those in the northern part of Luangwa District, and those with a reported history of antimalarial treatment. These data suggest microscopy should remain the gold standard for estimating malaria parasite point prevalence from household surveys for monitoring and evaluation purposes. Full article text.

A behavioral intervention to improve obstetric care - November 30, 2010 - 1:00 p.m.
BACKGROUND: Implementation of evidence-based obstetrical practices remains a significant challenge. Effective strategies to disseminate and implement such practices are needed.
METHODS: We randomly assigned 19 hospitals in Argentina and Uruguay to receive a multifaceted behavioral intervention (including selection of opinion leaders, interactive workshops, training of manual skills, one-on-one academic detailing visits with hospital birth attendants, reminders, and feedback) to develop and implement guidelines for the use of episiotomy and management of the third stage of labor or to receive no intervention. The primary outcomes were the rates of prophylactic use of oxytocin during the third stage of labor and of episiotomy. The main secondary outcomes were postpartum hemorrhage and birth attendants' readiness to change their behavior with regard to episiotomies and management of the third stage of labor. The outcomes were measured at baseline, at the end of the 18-month intervention, and 12 months after the end of the intervention.
RESULTS: The rate of use of prophylactic oxytocin increased from 2.1% at baseline to 83.6% after the end of the intervention at hospitals that received the intervention and from 2.6% to 12.3% at control hospitals (P=0.01 for the difference in changes). The rate of use of episiotomy decreased from 41.1% to 29.9% at hospitals receiving the intervention but remained stable at control hospitals, with pre-intervention and post-intervention values of 43.5% and 44.5%, respectively (P was less than 0.01 for the difference in changes). The intervention was also associated with reductions in the rate of postpartum hemorrhage of 500 ml or more (relative rate reduction, 45%; 95% confidence interval [CI], 9 to 71) and of 1000 ml or more (relative rate reduction, 70%; 95% CI, 16 to 78). Birth attendants' readiness to change also increased in the hospitals receiving the intervention. The effects on the use of episiotomy and prophylactic oxytocin were sustained 12 months after the end of the intervention.
CONCLUSIONS: A multifaceted behavioral intervention increased the prophylactic use of oxytocin during the third stage of labor and reduced the use of episiotomy. Full article text.
